Method of simultaneously coating and tempering glass at high temperature

Abstract

A method for simultaneously tempering and coating glass, including heating a glass substrate, depositing a textured buffer layer on the glass substrate, depositing a material on the buffer layer, depositing O2, and rapidly cooling the glass substrate by introducing a gas. This includes coating the glass substrate with crystalline sapphire or a low E film, for example.

1 . A method of simultaneously tempering and coating glass, comprising:
 heating a glass substrate;   depositing a textured buffer layer on the glass substrate;   depositing a ceramic material on the buffer layer;   depositing O 2 ; and   rapidly cooling the glass substrate by introducing a gas.   
     
     
         2 . The method as recited in  claim 1 , wherein the buffer layer is MgO. 
     
     
         3 . The method as recited in  claim 1  wherein the ceramic material is aluminum, the aluminum forming a thin film of Al 2 O 3  with the deposited O 2 . 
     
     
         4 . A method of tempering and coating glass with a low E film, comprising:
 heating a glass substrate;   depositing a textured buffer layer on the glass substrate;   depositing tin on the buffer layer, forming a tin oxide film;   doping the tin oxide film with fluorine; and   rapidly cooling the glass substrate by a gas.   
     
     
         5 . A method of simultaneously tempering and coating glass, comprising:
 heating a glass substrate;   depositing a photovoltaic absorber coating on the glass substrate;   depositing a conducting layer; and   rapidly cooling the glass substrate by introducing a gas.   
     
     
         6 . The method as recited in  claim 1  wherein the gas is O 2 , He, H 2 , Ar, or N 2 . 
     
     
         7 . The method as recited in  claim 4  wherein the gas is O 2 , He, H 2 , Ar, or N 2 . 
     
     
         8 . The method as recited in  claim 5  wherein the gas is O 2 , He, H 2 , Ar, or N 2 .
